Problem on cat5500 with DHCP server

Hi,

We have a strange problem with a cat5513 switch getting IP from DHCP server.

We have a cat5509 with 9-giga port as core switch and have a cat5513 switch branched off from core switch (cat5509). DHCP server is connected to core switch(cat5509) and a DHCP-client is connected to cat5513.

DHCP server and client are in same network.

DHCP client is having a problem getting an ip address from DHCP server from cat5513, but if we connect cat2900 to cat5513 and connect DHCP-client to cat2900 switch, DHCP-client get an IP from DHCP.

Hi all,

Is it possible that the long cable is beyond 100meters - thus longer than that supported by Ethernet (or is that just in half-duplex scenarios?). Or possibly electrical noise could be an issue - are you getting errors on the port when using the long cable in comparison to using the shorter one?
